WIND-SHIELD.

Specification of Letters Patent. Patented J 119 15, 1 915,

- Application filed June 17, 1914'. Serial No. 845,649;

To all whom it may concern:

Be it known that I, EDWARD P. BIDWELL, a citizen of the United States,residing at Monrovia, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in Wind-Shields, of which the following is a specification.

My invention relates to new and useful improvements in wind shields,automobiles, boats and other vehicles and resides in the provision of awind shield that is so constructedand arranged as to prevent theaccumulation of moisture thereon'so that the operator of the vehicle mayclearly see through the shield and thus avert possible accidents whichoften result through failure of the operator to see through a 'moistshield.

Another and more specific object is to provide a ,shield that consistsof a double pane mounted within a frame, said panes being spaced toprovide an air space and a heating element being arranged at the bottomof the space between the panes so that the panes will be heated andmoisture prevented accumulating thereon.

Another object is to provide a device of the character described that isof extremely simple construction, may be easily assembled anddisassembled and a so attached and detached to the vehicle, and which isinexpensive to manufacture.

The'above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out as claimed.

With reference to the drawings, wherein I have illustrated the preferredembodiment of my invention as it 1s reduced to practice, and throughoutthe several views of which similar reference numerals designatecorresponding parts, Figure 1 is a front elevation of my wind shleld,Fig. 2 is a horizontal sectional view showing the heatin element in thebottom of the shield, an Fig. 3 is a vertical sectional view takenthrough myimproved wind shield.

Referring to the drawings by characters of reference, the numeral 1designates as an entiretya rectangular frame which consists of verticalend bars 2 and horizontal top and bottom bars 3 and 4. The bars 2 areprovided at their longitudinal edges with 5 right angularly extendingflanges 5. Theflanges 5 on one of the bars 2 are arranged in pairs so'as to provide window pane receiving grooves, while the flanges 5 on theother of the bars 2 are arranged to c06perate with flanges 6 formed onthe longitudinal edges of a rectan ular strip 7 that are secured in anysuitab e manner upon the inner face of said last nained side bar. Thelast named of the side bars 2 is removable and said removable barisprovided with buttons 8 to be grasped to effect the removal. Mountedbetween the flanges 5 and '6 are panes of glass 9 and 10 which arespaced considerably and at their upper and lower edges engage withinchannel-shaped bars 11 and 12 which bars are carried-by the bars 3 and 4or may be formed by bending said bars 3 and 4 along their longitudinaledges into such channel shape.

The bars 3 and 4 are approximately semicircular in cross section andmounted within the lower bar 4: is a heating element designated 13 as anentirety which comprises a suitable cylindrical core in which is mounteda wire which is given a number of turns or in other words is coiledabout the core.

The wire is designated 14 and is connected I with a suitable source ofcurrent 15 at its free end. A one point switch 16 is connected in oneside of the circuit from the battery or other suitable source of current15 and is preferably arranged adjacent to the operators seat of avehicle, n0t shown, so that should the glass panes 9 and 10 become moistthe operator can readily close the circuit through the medium of theswitch 16 and the heating element 13 will heat the panes 9 and 10 thuspreventing moisture accumulating on the shield. V

, It isto be understood that any desirable form of electrical heatingelement may be employed and that the lower bar may be insulated after amanner not shown, in any suitable manner so as to support orrhouse theheating element. a

In practice, I have found that the form of my invention, illustratedrinthe drawings and referred to in the above description, as the preferredembodiment, is the most efficient and practical; yet realizin that theconditions concurrent with the adoption of my device will necessarilyvary, I desire to emphasize the fact that various minor changes indetails of construction, proportion and arrangement of parts may berecarried by the opposed bars, panes carried by the supporting loars andspaced from one another and a heating element carried by the lower ofthe bars and disposed below 10 the lower edges of the panes.

In testimony whereof I afiix my signature in presence of two witnesses.
